escribió: A mpeg file can be copied over 100 times faster than it takes to play it. The disk's speed therefore seems to be so much faster than needed for video, why is it even necessary to speed it up by reducing the error-correction? Because PVRs don't just play; they simultaneously record, from two sources on twin-tuner models, and have features such as live pause and action replay. So the disk may be having to deal with simultaneous multiple streams of data. -- (\__/) (='.'=) (")_(") |

Because the worst of the retrys on error correction with writes can see a significant glitch in the video file. When the error correction isnt as aggressive, the glitch is much less noticeable. |

So the disk may be having to deal with simultaneous multiple streams of data. That's only 3 or 4 times the load, but I can see that thrashing and re-seeking would slow it down a lot more. Constant thrashing for long periods causes wear and heating too, so I wonder if they are designed for that. -- Reply in group, but if emailing add one more zero, and remove the last word. |

I have just ordered one of these AV-GP drives as I was able to find one fairly cheap and needed a smaller drive to run my operating system off. Initially, I was sucked on by the low temperature and quicker read speeds, however have been put of a little by threads such as these on the net. Could anyone confirm whether or not they have used one of these drives as a boot drive within a computer? If so, have you noticed any behavioural characteristics different to, say, any other HDD? If the drive is unsuitable, i'd rather not bother removing it from the packaging and sort out a return a.s.a.p. |

None gave a problem. But I always check the SMART data first. Some had a disturbing maximum temperature (up to 80 Celcius). Perhaps somebody left the TV magazine on top, blocking the vents. |
